ROTARY PRINTING MACHINE Filed July 9, 1931 INVENTOR Patented a. 22, 1935 UNITED STATES PATENT OFFICE ROTARY PRINTING MACHINE Application July 9, 1931, Serial No. 549,597 In Great Britain September 1, 1930 2 Claims. (01. 270-37) This invention relates to improvements in rotary printing machines.

The main object of the present invention is to provide an arrangement which will enable a l stitched product (hereinafter referred to as the supplementary product) to be associated with a folded product (hereinafter referred to as the principal product) such for example as a photogravure supplement which is inserted in the fold of a newspaper.

According to the present invention there are provided means for associating the webs for forming the principal and the supplementary product, means for stitching the webs of the supplementary product before they are so associated, a cutting mechanism which severs the webs into prod- -ucts, and a folding mechanism which folds the products.

The invention is illustrated in the accompanying diagrammatic drawing as applied to a printing machine which is two folders wide; the mechanism according to the present invention is shown applied to associate a supplementary product and with the webs led to one of the folders.

l, 2, 3, 4 indicate the webs for forming the supplementary product: these webs are led around guide rolls 5 to a pair of associating rolls 6 whence they pass to stitching cylinders l, 8 which insert stitches in the associated webs. The stitching mechanism includes staple forming members, one of which is indicated at 23, suitably secured to the frame of the machine, and the cylinders 1 and 8 carry coacting staple forming and clinching members indicated respectively at 24 and-25. One

of the spools of wire of which the staples are formed is indicated at 26. The stitched webs are then led around guide rolls 9, I 0 and H, l2 to cutting and folding cylinders l3, M respectively. As these stitched webs enter between the cylinders they are associated with webs l5, for forming the principal product, which pass from a former l6, draw rolls l1, l8 and through guide rolls I9, 20.

The associated supplementary and principal webs are now severed into products by the cutting cylinder l3 and the severed products folded off into the nip of folding rollers 2|, 22 whence they pass toany suitable kind of delivery device.

When the webs l--4 are to form a photographic supplement they would be drawn from an intaglio printing machine. If it be desired to insert an unstitched supplement, the stitching mechanism could obviously be rendered inoperative.

What I claim is:

1. In a folder for a printing machine, a frame.

separate formers supported in the frame and adapted to longitudinally fold separate webs from the printing machine, a cutting and folding mechanism for each former operably supported in the frame, means in the frame for associating 5 the longitudinally folded printing machine webs and leading these associated webs to one of the cutting and folding mechanisms, a complete stapling mechanism operably supported in the frame independently of the cutting and folding 10 mechanism, a plurality of supplemental webs from a source external of the printing machine, means for leading the supplemental webs to the folder. means for associating the plurality of supplemental webs in advance of the stapling mecha- 15 nism, means operably supported in the frame and interposed between the stapling mechanism and a cutting and folding mechanism for leading the associated supplemental webs from the stapling mechanism to the folding and cutting mecha- 20 nisms where the associated stapled supplemental webs are associated with the associated printing machine webs and folded, cut and delivered therewith.

2. In a folder for a printing machine, a frame, 25 separate formers supported in the frame and adapted to longitudinally fold separate webs from the printing machine, a cutting and folding mechanism for each former operably supported in the frame, means in the frame for associating the 39 longitudinally folded printing machine webs and leading these associated webs to one of the cutting and folding mechanisms; a stapling mechanism operably supported in the frame independently of the cutting and folding mechanisms and 35 including staple forming members, and coacting stapling cylinders operably supported in the frame, a plurality of supplemental webs from a source external of the printing machine, means for leading the supplemental webs to the folder, means operably supported in the frame for associating the plurality of supplemental webs ahead of the stapling cylinders, means operably supported in the frame and interposed between the stapling cylinders and the cutting and folding mechanism for leading the associated supplemental webs from the cooperating stapling cylinders to the folding and cutting mechanisms where the associated stapled supplemental webs are associated with the associated printing machine webs and folded, cut and delivered therewith.
